A modeled time-and-cost comparison of AI-assisted and manual medical chronologies. The manual side is built from cited public industry figures; the Chronos side uses clearly-labeled placeholders pending measured data.
Producing a medical chronology by hand is one of the most time-consuming steps in a personal-injury or medical-malpractice case. A single case can span a few hundred to several thousand pages, and published estimates put experienced manual review at roughly 50 pages per hour for clean records — so a mid-sized case can absorb 10, 20, or more hours of skilled paralegal time before a usable timeline exists.
Using a representative 750-page case, a 50 pages/hour manual review speed, and a $45/hour loaded internal cost, the manual path models out to roughly 15 hours and ~$675 per case in labor — before turnaround delay. An AI-assisted path, using illustrative placeholder Chronos figures, models to a small fraction of that time and cost.
We deliberately avoid headline claims like "80% faster." Vendors across this category publicly cite reductions from 20–80 manual hours down to minutes or hours per chronology — we report those as third-party vendor claims, not verified fact. Chronos's own measured numbers will be inserted where marked. Until then, treat every Chronos-side figure here as an editable placeholder, not a promise.
Bottom line (modeled): The manual cost and turnaround of medical chronologies is real, sourced, and large. The size of the AI advantage depends on Chronos's measured performance, which we will publish transparently rather than estimate aggressively.
A transparent estimating model. Each variable is either a cited industry figure or a labeled assumption. Manual-side inputs are grounded in public sources; Chronos-side inputs are explicitly placeholders pending measured data.
| Variable | Value | Type | Basis / source |
|---|---|---|---|
| Representative case size | 750 pages | Assumption (editable) | PI/med-mal cases commonly run hundreds to several thousand pages. |
| Manual review & summary speed | 50 pages/hr | Cited industry estimate | Experienced reviewers ~50 pages/hr on clear records; slower for handwritten/complex. |
| Reviewer loaded internal cost | $45/hr | Derived from cited wage | BLS mean paralegal wage ~$32/hr (May 2024), grossed up for benefits + overhead. |
| Reviewer billing rate (alt. view) | $100/hr | Cited industry range | Litigation paralegal billing commonly $75–$120/hr. |
| Productive hours per working day | 6 hrs | Assumption | Realistic task-focused hours, not an 8-hour clock. |
| Chronos cost per page | $0.50/page | PLACEHOLDER | Per-page market context $0.05–$0.25/page; replace with real Chronos price. |
| Chronos processing / turnaround | 1 hr | PLACEHOLDER | Vendor claims cite minutes–hours; replace with measured Chronos turnaround. |
| Chronos human QA time per case | 1 hr | PLACEHOLDER / assumption | Residual attorney/paralegal review; replace with observed Chronos workflow time. |
Manual hours = pages ÷ manual speed Manual labor cost = manual hours × hourly cost Manual turnaround = manual hours ÷ productive hours/day AI software cost = pages × cost per page AI human cost = QA hours × hourly cost AI total cost = AI software cost + AI human cost AI total hours = processing/turnaround hours + QA hours AI turnaround = AI total hours ÷ productive hours/day Savings = manual − AI (cost, hours, turnaround)
Modeled estimate. Not measured Chronos data. Chronos-side figures use the placeholder values defined above.
Scenario A, 750-page case — Chronos side uses placeholder inputs
| Metric | Manual | Chronos (modeled, placeholder) | Difference (modeled) |
|---|---|---|---|
| Reviewer hours | 15.0 hrs | ~2.0 hrs (1 hr processing + 1 hr QA) | ~13 hrs less |
| Labor / software cost | ~$675 | ~$420 ($375 software + $45 QA) | ~$255 less |
| Turnaround (working days @ 6 hr/day) | ~2.5 days | ~0.3 days | ~2.2 days faster |
Manual = 750 ÷ 50 = 15 hrs × $45 = $675. Chronos = (750 × $0.50) + (1 hr × $45) = $375 + $45 = $420; hours = 1 + 1 = 2. All Chronos inputs are placeholders.
| Case size | Manual hours (@50 pg/hr) | Cost @ $45/hr (internal) | Cost @ $100/hr (billed) | Turnaround (@6 hr/day) |
|---|---|---|---|---|
| 300 pages | 6.0 hrs | $270 | $600 | ~1.0 day |
| 750 pages | 15.0 hrs | $675 | $1,500 | ~2.5 days |
| 1,500 pages | 30.0 hrs | $1,350 | $3,000 | ~5.0 days |
| 3,000 pages | 60.0 hrs | $2,700 | $6,000 | ~10.0 days |
This table uses only cited/derived figures (speed, rates) and is independent of any Chronos placeholder. It shows the size of the manual problem Chronos addresses.

| Measured average human QA time per case | [PLACEHOLDER — insert real Chronos measured data] |
| Measured cost per case / per page | [PLACEHOLDER — insert real Chronos measured data] |

| Sample size & methodology of measurement | [PLACEHOLDER — insert real Chronos measured data] |
At a modeled ~$255 saved per 750-page case and 10 cases/month, the model implies ~$2,550/month and ~$30,600/year in labor/cost difference, plus ~130 reviewer hours/month redirected. These figures move entirely with the Chronos placeholders and are illustrative only.
All figures retrieved June 2026. Industry sources describe general market conditions and third-party vendor claims and are not measurements of Chronos. Replace all placeholder slots with Mahlum Innovations' measured data before citing Chronos performance.
Methodology note. This report renders a modeled estimate: the manual side is reproducible from cited public figures, and every Chronos-side value is a labeled placeholder, never an invented or measured claim.
